Hello everyone!
Today we’ve got another quality of life update bringing a host of new features and changes for players both new and existing! But before we delve into the details we’d just like to say a big thank you for all the interest and support that’s been shown for Besiege’s upcoming space expansion: The Broken Beyond.
If you haven’t already, please wishlist the expansion as it really helps us out!
[dynamiclink href="https://store.steampowered.com/app/3639470/Besiege_The_Broken_Beyond/"]For this update, community modder dagriefaa has been working tirelessly on implementing some of the community’s most popular mod features and requests into the base game, so a huge thank you to him from all the team at Spiderling!
To start with, you can now remap hotkeys for multiple blocks at the same time, improving your ability to quickly customise your machine controls. The “Paint Bucket” has also received some attention, with changes that should make it much quicker and easier to apply & change the block skins you commonly use on your machines.

For less experienced players we’ve added a host of tutorials to The Splintered Sea expansion, that will teach you the fundamentals of building aquatic machines, from ships to submarines! We’ve also updated a bunch of the game’s block tooltips to make them more consistent and offer you more details of their stats.
[img src="{STEAM_CLAN_IMAGE}/7737949/4f4505ed55a8c8a8dfdd43c07aa132ab133dee6d.png"]
Both the Cannon & Water Cannon now have a higher maximum power of 3x, instead of the original 2, and new graphics options for higher FPS and Vsync have been added. These features and many more are all detailed down in the changelog below, so do take a look and don’t forget to wishlist The Broken Beyond, coming Q2 2026!
Cheers everyone,
Von
